SIMCOM 7080G 上的 SHCONN AT 命令失败

Question

我的 SIMCOM 是 7080G，固件更新为： 预计更新：1951B16SIM7080，B16V01 QCN:SIM7080G_P1.03_20201226 IMEI:860016041830931

我完全遵循以下中描述的 HTTP 过程： SIM7070_SIM7080_SIM7090系列_HTTP(S)_应用笔记_V1.02

设置一切正确，IP 正确，运营商和 PDP 连接良好。 当系统发出 AT+SHCONN 时，它总是给出 ERROR。

使用不同的 SIM 卡进行测试 使用不同的呼叫者 RxTx 软件。 一个是我自己的C++，琐碎， 第二个是 ATCommandTester 实用程序

我会附上日志。

提前致谢， 并致以亲切的问候， 奥拉西奥

在设置新实例之前，您是否尝试过使用“AT+SHDISC”断开任何先前的 http(s) 实例？
